I wasn't even talking about pigeons .. that was your little flight of

A racer of 50Km/hr pigeons releases 1 bird every 5 min

"a somewhat larger time" You are suggesting the
someone's watch is responding to the motion and
the finite speed of the birds shouldn't be considered.

I suggested nothing related to pigeons

Actually I don't think you ever said the racer's watch
wasn't going slower to explain his wifes observations
so for all I know your sense of reality is as strange
as your maths.

Sorry that you don't undersatnd Sr and Lorentz transforms. Go away and
study, and come back when you do.

<< It is clear that dt = d_tau in the particle's rest frame.
Thus, d_tau corresponds to the time difference between
two neighbouring events on the particle's world-line, as
measured by a clock attached to the particle (hence,
the name proper time). According to Eq. (1422), the
particle's clock

----> appears <-----

yes .. it does appear to .. because it is running slow (or rather its
projection into the inertial frame is running slow)

to run slow, by a factor gamma(u), in an
inertial frame in which the particle is moving with velocity u.
This is the celebrated time dilation effect. >>

...Contrary to your arrogant assertions that something
more is afoot than a mere path delay

It is more than path delay .. it is NOT an illusion .. time runs slower in
relatively moving frames tha ones own frame.

Its not an optical illusion that we simply see it slower beacuse of delays
in the light getting to us from the clock we're looking at.

... and it
works the same for pigeons and light.

Yes .. esp if they are very fast pigeons.

Please .. do some more reading on Lorentz transforms and SR.
